Hi all,
i new to xml and i have a xml-problem. Perhaps someone in this list can help
me.
i created a DTD and i created a kind of extension of this DTD in a separate
file.
This extension contains a company specific structure of data.
Other companies who uses the DTD too, should not be aware of this extension.
Consequently i had the idea to put this structure
in a separate file and use an optional external entity. In this way
maybe it is possible to omit the extension (file) when we deliver this DTD
to other companies
and no modification of the DTD is necessary.
Despite of serveral tries to realize it, i did not manage to do it. I'm not
sure if a optional external
entity is possible!?
Is this a possible?
Thanks in advance
Mirko
